The differential sensitivities of A beta, A delta and C fibres of rat vagus nerve to bupivacaine, etidocaine and AL-381 were studied in vitro. In A beta fibres, at 35-37 degrees C, 50 mumole litre-1 of the drugs had similar effects on the action potential amplitude, while at greater concentrations (100 and 200 mumole litre-1) the greatest mean depression of amplitude was seen with etidocaine (n...

The Formosan subterranean termite, Coptotermes formosanus Shiraki is currently one of the most destructive pests in the USA. It is estimated to cost consumers over US dollars 1 billion annually for preventative and remedial treatment and to repair damage caused by this insect. The mission of the Formosan Subterranean Termite Research Unit of the Agricultural Research Service is to demonstrate t...

This article is a review of the PhD Thesis of Malin Eriksson, entitled 'Social capital, health and community action - implications for health promotion.' The article presents a theoretical overview of social capital and its relation to health, reviews empirical findings of the links between social capital and (self-rated) health, and discusses the usefulness of social capital in health promotio...

It has long been recognized that the media play an essential role in democracy. However, even in the absence of censorship, the government may in‡uence news content by maintaining a “cozy”relationship with the media. This paper develops a simple model of democratic politics in which the actual freedom of the press is endogenous. In equilibrium, the features of the media market determine the abi...

In a remarkable empirical study of 168 U.S. manufacturing plants, James Medoff and Jon Fay (1985) have examined the magnitude of labor hoarding during economic contractions. They found that during its most recent trough quarter, the typical plant paid for about 8 percent more blue-co&t hours than were needed for regular production work. Some of these hours were used for other worthwhile work, a...

Disorder in the 1D spinless Holstein model. Abstract: We investigate a spinless fermion system on a one dimensional lattice interacting locally with the optical modes of a quantized phonon field: the Holstein model. The system is shown to have a disordered ground state, for small enough coupling, at any density. This is in contrast to the non quantized phonon case, the static Holstein model, wh...

This study aims at exploring ink spreading, which causes significant colour deviations in ink-jet printing. We present a method for investigating this phenomenon by considering only a limited number of cases. Using a combinatorial approach based on Pólya’s counting theory, we determine a small set of ink drop configurations which allows to deduce the ink spreading in all other cases. This impro...

[Abstract] Is tax evasion beneficial or harmful to growth? We approach this question by extending Persson and Tabellini’s (1994) growth model to a plausible world where individuals differ not only in terms of their skill in earning income but also in terms of their skill in concealing income from the tax authority. The Persson-Tabellini model identifies a fundamental tradeoff for redistribution...

A new species of the genus Paravillersia Kuznetsov, 1978 (Acari: Stigmaeidae), P. jamaliensis Khaustov sp. nov. is described from mosses on fen in Western Siberia, Russia. The supplementary description of Paravillersia grata Kuznetsov, 1978 is provided based on the type material.
